Abraham model correlations for ionic liquid solvents: computational methodology for updating existing ion-specific equation coefficients

ABSTRACT

The computational methodology for updating existing values of Abraham model ion-specific equation coefficients is illustrated using published experimental solubility and partition coefficient for solutes dissolved in 1-ethyl-3-methylimidazolium trifluoroacetate, 1-butyl-3-methylimidazolium trifluoroacetate and 1-hexyl-3-methylimidazolium trifluoroacetate. The updated Abraham model ion-specific equation coefficients that are reported for the trifluoroacetate anion are based on 51 experimental values.
